Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for high ammonia nitrogen and high salinity. Background Technology

[0002] Industries such as chemical, pharmaceutical, pesticide, landfill leachate treatment, and rare earth smelting generate large quantities of complex wastewater with high ammonia nitrogen and high salinity. Currently, the treatment of high ammonia nitrogen and high salinity wastewater typically employs a combined process of "pretreatment + biological treatment + advanced treatment." However, when the wastewater has excessively high salinity and ammonia nitrogen concentrations, it severely inhibits microbial activity, leading to poor or even ineffective traditional biological treatment methods. Against this backdrop, physicochemical methods centered on low-temperature evaporation demonstrate significant advantages. Low-temperature evaporators can evaporate water from wastewater at relatively low temperatures, thereby achieving effective separation of water from dissolved salts, ammonia nitrogen, and other pollutants.

[0003] However, existing low-temperature evaporation equipment, especially in batch processing or intermittent feeding modes, suffers from a common but long-neglected technical challenge when treating high-ammonia-nitrogen and high-salt wastewater: as the evaporation process progresses, the wastewater level continuously decreases, leading to a sharp decline in heat source utilization and significant energy waste. Specifically: in the initial stage of evaporation, the wastewater level is high enough to completely submerge the heating surface of the heat exchanger, maximizing the heat transfer area and maximizing the heat exchange efficiency between the heat source (such as hot water or steam) and the wastewater, resulting in a rapid evaporation rate. As water evaporates, the wastewater level gradually decreases. When the level drops below the point where it can no longer completely cover the heat exchanger, the portion of the heat exchanger surface exposed to the gas phase is no longer in contact with the liquid. This exposed heating surface primarily heats the air within the evaporation chamber, rather than being used to evaporate the wastewater. Therefore, a significant amount of heat energy is wasted on heating the gas, causing the system's effective thermal efficiency to decrease significantly as the liquid level drops. Summary of the Invention

The projection of all injection tubes 8 on the horizontal plane is evenly distributed around the axis of the storage shell 2. The number of nozzles 91 on the same injection tube 8 can be selected by the operator. All nozzles 91 on the same injection tube 8 are distributed along the axis of the injection tube 8, and the heating height of the heating module is flush with the uppermost injection tube 8. In actual use, it is necessary to ensure that the height of the wastewater level in the storage shell 2 does not exceed the uppermost injection tube 8.

[0026] Please see Figure 3 Several injection tubes 8 are spirally distributed along the outer side of the rotating shell 7, and the height difference between any two adjacent injection tubes 8 is the same, which is used to improve the uniformity of drug distribution in the storage shell 2.

[0027] Please see Figure 8 and Figure 9 The triggering component includes: a first moving rod 10, the number of which is the same as the number of nozzles 91, which are slidably connected to the corresponding nozzles 91. A sealing member 11 is fixedly connected to the first moving rod 10. Both the sealing member 11 and the nozzle 91 are provided with a diameter-changing part. The diameter-changing part of the sealing member 11 is used to block the diameter-changing part on the corresponding nozzle 91, and a first spring is fixedly connected between the sealing member 11 and the nozzle 91; an unlocking member 12, the number of which is the same as the number of injection tubes 8, which are slidably connected to the corresponding injection tubes 8, and a second spring is fixedly connected between them; and a second moving rod 13, the number of which is the same as the number of the first moving rods 10, which are fixedly connected to the corresponding first moving rods 10. The second moving rod 13 is located inside the corresponding injection tube 8, and the unlocking member 12 is used to squeeze the corresponding second moving rod 13.

[0028] In the above scheme, the first moving rod 10 is located inside the corresponding nozzle 91; the first spring on the sealing member 11 is always in a charged state; the unlocking member 12 is composed of symmetrically distributed serrated plates, a disc, and a cylinder with several flow holes, wherein the disc is located away from the central axis of the liquid storage shell 2, the cylinder is located close to the central axis of the liquid storage shell 2, the serrated plate is located between the disc and the cylinder, and both the serrated plate and the disc are located inside the corresponding injection tube 8, the cylinder is partially located inside the injection tube 8 and partially located outside the injection tube 8, the serrated plate of the unlocking member 12 is used to squeeze the second moving rod 13; the second spring on the unlocking member 12 is always in a charged state; the second moving rod 13 is located above the corresponding first moving rod 10.

[0029] Please see Figure 9 Both the sealing element 11 and the nozzle 91 are provided with a diameter-changing part. The diameter-changing part of the sealing element 11 is located at its lower end, which is used to improve the sealing between the two.

[0030] Please see Figures 4-8 The triggering component also includes: a moving ring 14, slidably connected to the liquid storage chamber 9; a squeezing rod 15, the number of which is the same as the number of injection tubes 8, all fixed to the moving ring 14, the squeezing rod 15 and the corresponding unlocking member 12 are both provided with inclined surfaces, and the inclined surface on the squeezing rod 15 is used to squeeze the inclined surface on the unlocking member 12; a second electric push rod 16, fixed to the upper side of the sealing cover 3, the telescopic end of the second electric push rod 16 passes through the sealing cover 3 and the fixing ring 71, and the telescopic end of the second electric push rod 16 is fixed with a ring that is rotatably connected to the moving ring 14.

[0031] In the above scheme, the moving ring 14 is located at the upper part of the liquid storage chamber 9; the length of the squeezing rod 15 changes with the position of the corresponding injection tube 8; the inclined surface on the unlocking member 12 is located on the side of its cylinder close to the axis of the liquid storage shell 2; the inclined surface on the squeezing rod 15 is located on its lower side; in actual use, the second electric push rod 16 can be set to a plurality of circumferentially evenly distributed ones to improve the uniformity of the force on the moving ring 14.

[0032] Please see Figure 6 There is a gap between the inner wall of the moving ring 14 and the inner wall of the rotating shell 7, and there is also a gap between the squeezing rod 15 and the inner wall of the rotating shell 7, to ensure that the liquid in the storage chamber 9 can flow over the moving ring 14.

[0033] The specific workflow of the above scheme is as follows: When this device is needed to treat pretreated wastewater with high ammonia nitrogen and high salinity (hereinafter referred to as wastewater), the operator connects the exhaust pipe of the sealing cover 3 to the external exhaust device and the liquid inlet pipe on the first movable shell 6 to the wastewater flow pipe, so that the wastewater flows into the first movable shell 6 and flows into the storage shell 2 through the drain pipe on the lower side of the first movable shell 6. When the liquid level of the wastewater in the storage shell 2 reaches the specified height (this position is determined by the operator, but should not exceed the uppermost liquid injection pipe 8), the drain valve in the drain pipe on the first movable shell 6 is closed (some wastewater will still be stored in the first movable shell 6). Then the heating module is started, and the heating module heats the side wall of the storage shell 2, thereby heating the wastewater in the storage shell 2.

[0034] While heating the wastewater in the storage tank 2, the external air extraction device is activated to extract the gas from the storage tank 2, creating a negative pressure environment inside the storage tank 2. This lowers the boiling point of the wastewater in the storage tank 2, achieving the purpose of low-temperature evaporation. During this process, the operator activates the drive module, which drives the rotating shell 7 and all the injection pipes 8 on it to rotate synchronously. The rotating shell 7 and all the injection pipes 8 work together to stir the wastewater in the storage tank 2 during rotation, increasing the uniformity of the wastewater's heating. At the same time, during the rotation of the rotating shell 7, the rotating shell 7 drives the moving ring 14 and the extrusion rod 15 inside it to rotate synchronously. The moving ring 14 rotates relative to the ring on the telescopic end of the second electric push rod 16 during rotation, and the rotating shell 7 rotates relative to the fixed ring 71 during rotation.

[0035] During the rotation of the rotating shell 7, the operator adds medicine into the storage chamber 9 through the dosing tube on the fixed ring 71. At the same time, the second electric push rod 16 is activated, causing the telescopic end of the second electric push rod 16 to drive the moving ring 14 to move downward synchronously. The moving ring 14 drives all the squeezing rods 15 on it to move downward. During the downward movement, the squeezing rods 15 squeeze the corresponding unlocking member 12 through their inclined surfaces, causing the unlocking member 12 to move away from the axis of the storage shell 2. During the movement, the unlocking member 12 squeezes the second spring. At the same time, the unlocking member 12 squeezes the corresponding second moving rod 13, causing the second moving rod 13 to drive the corresponding first moving rod 10 to move upward. The first moving rod 10 drives the sealing member 11 to move synchronously, and the sealing member 11 squeezes the corresponding first spring during the movement.

[0036] As the sealing member 11 moves upward, the variable diameter part of the sealing member 11 gradually loses contact with the variable diameter part of the corresponding nozzle 91. When the two completely lose contact (the unlocking member 12 can still continue to move), the sealing member 11 no longer seals the corresponding nozzle 91, allowing the nozzle 91 to connect with the corresponding injection pipe 8. The liquid in the storage chamber 9 can flow into the storage shell 2 through the nozzle 91. When the moving ring 14 moves downward to its limit position, the inclined surface on the unlocking member 12 contacts the side wall of the corresponding squeezing rod 15. At this time, the medicine can flow into the injection pipe 8 through the through hole on the unlocking member 12, and then into the storage shell 2. After the medicine is added, the operator controls the second electric push rod 16 to drive the moving ring 14 to move upward. The moving ring 14 drives all the squeezing rods 15 to move upward synchronously, so that the squeezing rods 15 gradually separate from the corresponding unlocking member 12.

[0037] After the unlocking member 12 separates from the corresponding squeezing rod 15, the unlocking member 12 moves towards the axis of the liquid storage shell 2 under the action of the second spring on it. At the same time, the sealing member 11 drives the corresponding first moving rod 10 to move downward synchronously under the action of the first spring on it. During the movement of the sealing member 11, the variable diameter part of the sealing member 11 gradually contacts the variable diameter part of the corresponding nozzle 91. When the unlocking member 12 returns to the initial position relative to the corresponding injection tube 8, the first moving rod 10 and the sealing member 11 move downward synchronously to the limit position. At this time, the sealing member 11 re-seals the corresponding nozzle 91.

[0038] During the heating process of the wastewater in the storage tank 2, as the wastewater in the storage tank 2 gradually evaporates, the liquid level of the wastewater in the storage tank 2 also gradually decreases. Then, the staff starts the first electric push rod 5, and its telescopic end drives the first moving shell 6 to move downwards in sync. During the movement, the first moving shell 6 squeezes the wastewater remaining in the storage tank 2, forcing the liquid level of the wastewater in the storage tank 2 to rise, ensuring the contact area between the wastewater in the storage tank 2 and its inner wall, further improving the evaporation rate of the wastewater, and at the same time improving the heat utilization rate.

[0039] When the wastewater in the storage tank 2 is reduced to a certain volume (after solid impurities begin to precipitate from the wastewater in the storage tank 2), the staff releases the remaining wastewater through the discharge valve on the storage tank 2. After the wastewater is completely released, the staff controls the first electric push rod 5 to drive the first moving shell 6 to return to its initial position. At the same time, the staff opens the drain pipe on the first moving shell 6 to replenish the wastewater in the storage tank 2, and then continues to treat the wastewater according to the above process.

[0040] After the device has been used for a specified period (which is selected by the staff), the drive module and other parts should be shut down, and the wastewater in the liquid storage tank 2 should be completely drained before the device is cleaned and maintained in preparation for subsequent use. Example 2

[0041] Based on Example 1, this example further optimizes a wastewater treatment device with high ammonia nitrogen and high salinity.

[0042] Please see Figures 2-4 It also includes: a second movable shell 17, which is slidably connected to the heating shell 4 and is connected to the liquid storage shell 2; a third electric push rod 18, which is fixed to the bracket 1 and whose telescopic end is fixed to the second movable shell 17; and a deformation shell 19, which is disposed on the second movable shell 17 and is fixed to the liquid storage shell 2, for guiding the solution in the liquid storage shell 2.

[0043] In the above scheme, the second movable shell 17 is located outside the heating shell 4; in this embodiment, the liquid storage shell 2 is not provided with a bottom cover, and the lower side of the liquid storage shell 2 is sealed by the second movable shell 17; multiple third electric push rods 18 can be set in a circumferentially evenly distributed manner during actual use to improve the uniformity of force on the second movable shell 17; the deformation shell 19 is located inside the liquid storage shell 2, and the contact position between the two is located below the bottommost injection pipe 8; in this embodiment, the deformation shell 19 is flexible, and the middle part of the deformation shell 19 is fixedly connected to the second movable shell 17.

[0044] The specific process of the above scheme is as follows: When it is necessary to drain the residual wastewater in the storage tank 2, the staff activates the third electric push rod 18. The telescopic end of the third electric push rod 18 drives the second moving shell 17 to move downward synchronously. During the downward movement of the second moving shell 17, the middle part of the deformable shell 19 moves synchronously, causing the deformable shell 19 to deform under tension. This deformable shell 19 deforms into a conical shell shape, thereby guiding the residual wastewater and crystals in the storage tank 2 and reducing the amount of residual wastewater in the storage tank 2.

[0045] After the wastewater in the storage tank 2 is drained, the staff controls the third electric push rod 18 to move the second moving shell 17 upward. During the movement, the second moving shell 17 reduces the tension on the deformable shell 19, thereby relaxing the deformable shell 19. At the same time, during the process of replenishing wastewater into the storage tank 2, the wastewater in the storage tank 2 squeezes the relaxed deformable shell 19, causing the deformable shell 19 to return to its initial shape for subsequent use. Example 3

[0046] Based on Example 2, this example further optimizes a wastewater treatment device with high ammonia nitrogen and high salinity.

[0047] Please participate Figure 4 The deformable shell 19 is provided with a flexible part and a rigid part. The flexible part is fixedly connected to the liquid storage shell 2, and the rigid part of the deformable shell 19 is slidably connected to the second movable shell 17. The rigid part of the deformable shell 19 is in the shape of a round tube and is located on its lower side.

[0048] Please participate Figures 2-4 It also includes: a connecting pipe 20, which is fixed to the lower side of the second movable shell 17 by a connector, and the rigid part of the deformable shell 19 slides inside the connecting pipe 20; a fourth electric push rod 21, which is fixed to the connecting pipe 20 by a fixing bracket, and the telescopic end of the fourth electric push rod 21 is fixed to the rigid part of the deformable shell 19.

[0049] The specific workflow of the above scheme is as follows: During the downward movement of the second movable shell 17, the transmission connecting pipe 20 of the second movable shell 17 and the fourth electric push rod 21 move downward synchronously. When the second movable shell 17 moves downward to the limit position, the operator controls the fourth electric push rod 21 to drive the rigid part of the deformable shell 19 to move up and down repeatedly, so that the flexible part of the deformable shell 19 is repeatedly deformed, thereby shaking off the impurities adhering to the flexible part of the deformable shell 19 and reducing the amount of impurities remaining on the deformable shell 19.

[0050] After the liquid in the storage tank 2 is completely drained, the staff repeats the above operation to reset the second movable shell 17 to the initial position and controls the fourth electric push rod 21 to move the rigid part of the deformable shell 19 to reset the rigid part of the deformable shell 19 relative to the connecting pipe 20 to the initial position for subsequent use. After the reset is completed, the above operation is repeated to continue treating the wastewater.

[0051] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in the appended specification.
